As shown in Figure 3 the main portion of the link extends into Yan opening 53 formedin the implement Vsupporting frame 49. The lower end of the frame 49 is provided with extensions 54 and 55 carrying hoe members 56 and 57, respectively.

The link 48 is provided upon its upper and lower faces with the lugs 58 and 59, respectively. A compression spring 60 has its lower end fitting around lug 58 and its npper end around rod 61 which latter is threadedin place in the frame and locked against movement by nut 62. The washer 63 bears upontheupper end of spring 60 and is adjusted by means of nut 64. A similar spring 65 bears against the lower face of link 4 8 surrounding stud 59. The lower end of this spring 65 surrounds rod 66 and is supported by washer 67, adjusted by nut`68.

As best shown in Figure 1, the upper end of the implement carrying frame 49 has secured thereto the bifurcated end 69 of the rod 70.k This rod 70 extends through a sleeve 71 pivotally secured to the housing 38.

The spring 72 is fitted upon rod 70 between sleeve 71 and the bifurcated portion 69. The spring 7 3 is vfitted upon the outer end of rod 7() V'and is held against the sleeve 71 b y washer 74 and nut 75. The bracket 76 is secured to housing 38 by nut 76. The inembei' 77 is pivotally secured at 78 to the lower Yend of the-bracket 76. The stud 7 9 is secured tofmeniber 77 and passes through the lower Vend 'ofbracket 7 6. The spring 80 surrounds this 'stud and is held in place by nut 81. 'Le'vers 82 and links 83 are provided whereby the housing 38 and hoe assembly may be swungy about ,theishaft 24. These features -do'iiot form a part of the present invention and will not be described in detail.

In the operation of the power driven hoes, power is supplied to the cross shaft 24 from the engine through bevel-gear 25 and shaft V26. The'power is transmitted through the shaft 37 to the short cross shaft 41 and the cranks. 43 and 45 describe a circular movement. Due to the connection of the upper l ends of the implement supporting frames ,Y describe a circular with the housing 38 through the rod 70,

sleeve 71 and the associated springs, the hoes upon the lower ends of the frames do not ath but an approxifmately elliptical pat the greater axis of -the ellipse being approximately parallel to the ground or slightly inclined thereto.

` The soil is engaged by the hoes and thrown by them due to their rapid movement. Soil engaged by the rearmost hoes 57 is thrown against the back of h'oe 56. The soilY from hoe 56 Visthrown against themember 77.

Should the hoes engage a stone or other obstacle, the springs 72 and'73 will yield in suchy manner asis necessary to prevent horizontal movement of the hoes regardless of the continued movement of the crank. The springs 60 and 65 will yield and the links 48 will move relative to the main implement supporting frames. The implements themselves may thus remain substantially immovable even though the cranks continue to rotate. The member 77 may also yield when necessary, the spring 80 being compressed during the yielding movement and serving to lreturn the member to normal position after the obstacle is passed.

The construction shown is adapted to accomplisha rapid and thorough mulching action upon the soil and is so constructed as to yield when striking relatively hard or immovable objects thus avoiding injury not only to the implements but to the cultivator itself.

The construction is simple and may be manufactured at a relatively small cost and may be applied to cultivators of the type shown or other cultivators adapted to use movable power operated hoes or similar devices.

l. claim:

1. In a power cultivator, a power driven crank, a hoe supporting member and hoe carriedby said crank, and a yielding connection between the hoe supporting member and a lixed portion ofthe cultivator whereby movement of the hoe supporting member and hoe is limited, said yielding connection resisting movement in either direction from a normal position.

2. In a power cultivator, a power driven crank, a hoe supporting member and hoe carried by said crank, a sleeve pivotally secured to a lixed portion of the cultivator, a rod pivotally secured to the hoe supporting member 'and extending through the sleeve,

vand springs upon the rod and engaging opposite sides of the sleeve to yieldingly resist movement of the rod relative to the sleeve.

3. An implement supporting member comprising a main frame having an opening therein, a link pivotally connected to one side of the opening and extending therein, the link being provided with a guide flange fitting within a recess upon the opposite side of the opening, and means for yieldingly maintaining the link in position relative to the frame.

4. An implement supporting member comprising a main frame having an opening therein, a link pivotally connected to one side of the opening and extending therein, thelink being provided with a guide flan e fitting within a recess upon the opposite side of the opening, and compression springs supside of the opening andvextending therein, the link being provided with a guide flange fitting Within a recess-upon the opposite side of the opening, and compression springs supported Within the opening andengaging opposite sides of the link to resist movement thereof relative to the freine, the link being provided with nieans for connecting the frame to driving means, andthe frame beingl provided With meansfor vthe attachment of ,10 implements thereto.
